HgTe Nanocrystals Carrier Density and Its Tuning

Small Structures, EarlyView.
The review discusses methods that control the carrier density of HgTe nanocrystals that are relevant for infrared sensing. Strategies at the nanoscale (surface chemistry, size…) and device level (gate, remote doping) are both discussed. HgTe nanocrystals (NCs) are now an established material for colloidal optoelectronics.

M(III) Site‐Driven Structural Engineering on Lead‐Free Layered Double Perovskite Nanocrystals with Enhanced Photoelectrochemical Activity

Small Structures, EarlyView.
The first‐ever lead‐free Co‐based layered double perovskite nanocrystals, namely, Cs4CoBi2Cl12 and Cs4CoSb2Cl12, are successfully synthesized as attractive photoelectrodes for photoelectrochemical reactions. Upon effective lattice engineering at the trivalent cation site, the as‐synthesized Bi‐based NCs exhibit a clear enhancement in the photocurrent ...

Metasurface‐Assisted Optical Transparency of a Continuous Metal Film

Small Structures, EarlyView.
Herein, a general strategy for realizing transparent conductors by sandwiching a continuous metal film between two metasurfaces is presented. A coupled‐mode theory model is developed to reveal the underlying physics and identify the optimal conditions.

Properties, mechanisms, and perspectives of ultrafast laser modifications in silicate glass volume

International Journal of Applied Glass Science, EarlyView.
Abstract Ultrafast laser irradiation of glass enables highly localized structural transformations within the material's bulk, unlocking diverse applications in photonics, data storage, and microfabrication. Here, we provide a concise yet comprehensive overview of the main types of femtosecond laser‐induced modifications in silica‐based glasses (Types I,
